Application filed February 25, 1914. Serial no. sates? To all whom it may concern:

Be it known that I, EUGENE AMBnozY, a subject of the King of Hungary, residing at New York, in the county ofNew York and State of New York, have invented certain new and useful Improvements in struction, of which the following is a specification. i I

This invention relates to ship building, and its primary object is to provide a hull structure having improved supporting and bracing means, to insure increased strength and rigidity, and to concentrate the impact and thrust-resistance at. the longitudinal center of the vessel, and thus toequalize lateral strain.

The main characteristic feature of the inventionis the employment of a verticallydisposed central partition wall or bulk-head, alinedwith the vessels heel, and constituting a main central longitudinal stay extending throughout the length of the vessel, and serving as a central support for the side plating ribs, and their transverse bracing means. o

' The invention also includes improved means for rigidly connecting the several sections of which the main central stay or partition is composed,-,and for supporting the deck stanchions, ribs, braces, and other elements. constituting the general structure of the shipshull; and various detail features of constructiomafl of which will be fully described hereinafter, in connection with the accompanying drawings which form a part of-this specification, and set forth and defined in the appended claims.

in the drawings: Figure 1 is a vertical portion of the bow of a ship embodying the invention. Fig. 2 is a horizontal section of the same. Fig. 3 is a vertical transverse section of thevessel il1us-' trating certain of its inclined struts and braces in elevation. Fi 4 is a vertical section on an enlarged scale ta (en on the line H of Fig. 2. Fig. 5 is a horizontal section, on an en: larged scale, on the line 5- of Fig.3 looking upward. Fig. 6 is a section on the line 6 6 of Fig. 2. Fig...7 is a det'agil perspective view the line 7" of Fig. 2,

Fig. 8 is a detail elevation on an eniarged showing. the of securing the Boat Contions 2 which make sectional.

crossed struts orbraces. Fig. 9 is a plan view, partly in horizontal: section of the parts shown in Fig. 8. Fig. 10 is a fragmentary elevation of the lower portion of thevessel hull, the central partition being in transverse section, and showing a modified form of floor structure. Fig. 11 is a detail perspective view partly in section illustrating the angle plates employed.

The reference numeral 1 designates a vertical' longitudinal partition supported centrally of the vessels length, and dividing the interior of the hull into two compartments designated respectively by the letters A and B. This-central longitudinal verti cal partition extends throughout the length of the hull, and is made up of plate-sections, or units each comprising a plurality of alined plates 2, connected and secured by the means hereinafter described.- o

As bestshown in Fig. 3, the deck beams designated byth'e numeral 3 are supported by stanchions 4, which space them apart, and

said beams are secured to; the central stay or partition 1 by said partition and to the beams, as best seen in Fig. 6, the horizontal members 5 of said connecting braces being riveted to the beams,

and theirvertical flanges 6 to the partition 1.

Fig. 11, the plate secup the central longi- As best shown in tudinal partition 1 abut one'another sidev by side and at their ends, the end joints 7 beangle bracessriveted to mg in staggered relation as shown in Fig. 25-;

The platesections 2 are held in properrelation to each other and are secured to the beams 3 by the angle brackets above 'described (see Fig. 11) each comprising the horizontal member 5 and the vertical mem her 6 formed integral with the member 5 and having vertically-disposed slots 10 into which the floor beams 3 exten v I The angle plates comprising the members 5, and 6 are securely riveted as at 11 to both the central parti ion and to the several beams. On the underside of each'beam3 nd secured thereto at cams area ngle plates t e angle bracketsh-b the floor beams 3 are 1 ee Fi s, 3 and a As the cqnaeeneas for each floor of the structure with the coir 9, between which and the inner en s of said its it is not deemed necessary to specifically describe more than one of sa d floor supports or connections.

Any desired number of decks or floors may be provided within the hull, the drawing showing a series of eight floors above the ships bottom. At convenientpoints 1n the supporting partitions along the main thoroughfares on each deck are arranged doors 11 The outer ends of the various deck beams 3 are suitably secured to the side plating of the vessel, and the latter is reinforced by any required number of stringers 12 firmly riveted to the plating and extending, longitudinally throughout thelength of the vessel between the decks or floors as clearly shown in Fig. 3.

The central vertical partition 1 is braced to the transverse frames by a series of diagonallv-disposed struts or braces 13'and 14 crossing each other firmly riveted together and to'brace the sides of the vessel as well as the central partition 1.

Each of the decks is supported by the stanchions 4 as above stated as well as by knees 15, the latter being disposed in opposite directions on either side of the central partition 1 with their upper ends attached to the deck beams 3, and having their lower ends bifurcated as shown in Fig. 5, for at tachment to vertical angle members 15 disposed between the floors and secured to the central bulk-head 1. In addition to the deck beams 3 being supported by the central partition 1 and at their outer ends by the sides of the vessel, they are supported and braced intermediate the vessel sides and the partition 1 by the stanchions 4, and at the points where the stanchions are provided, the deck beams are intersected by deck-stringers extending longitudinally of the vessel. Each of these deck-stringers comprises (see Fig.

7) upper and lower angle-bars 17. an upper bar and a lower bar being placed on each side of. and riveted to a vert cal bar 19. At the points where the stanchions 4 intersect with these deck-stringers and the deck beams 3, said stanchions have disks or heads 20 (see Fig. 4) which are riveted to the angle bars 17 of the deck-stringers. The floors comprise spaced members 2122 connected by inclined struts 23 disposed at opposite inclinations to afford rigidity of construction and brace the floors against strain in all directions. (See Fig. 3.)

As illustrated in' Figs. 8 and the several.

inclined braces 13 and 14 are off-set at their points of juncture shown at 24, thus adding to the strength of their connection and adapting them to ,be secured to adjacent supporting members of the hull structure on opposite sides of the latter as shown in he specific construction of the angle plates emploved to connect the floor beams to the central partition 1' constitutes a feature of importance in the present invention, the slots in the vertical members of said angle plates receiving the floor beams as above stated, and the horizontal members of said plates extending at right angles to the vertical members are in convenient position for their attachment to adjacent supporting parts.

A modified construction of the bottom of the vessel is shown in detail in Fig. 10 and is in the form of a double-floor. each formed of spaced upper and lower members braced by cross-struts 23. the upper and lower floors being spaced apart by longitudinal I-beams 26 interposed betweenthe floors.

From the construction as tlbQTC described,

it will be apparent that the central vertical longitudinal partition 1 constitutes the main support or fopndation for all of the transverse beams which support the side plating, ribs, and floor supports, and that substantially all of the parts named may be said to be suspended from such central longitudinal support. As shown in Figs. 3 and 10, the said central partition 1 is extended down so as to form the keel f-the boat hull.

The central partition, beams. ribs. and other elements making up the hull structure are preferably covered with asbestos applied in any suitable manner. and I also preferably provide a filling of concrete (not shown) between the floor members 2122.

The improved constructiomail'ords rigid and substantial hracings for the ressel both laterally and longitudinally. all strains or impact being directed toward the longitudinal center of the hull.

Having thus fully described my invention and in what manner the same is designed tor use. what I claim as new is';-

-1.- A ships hull, comprising the combination with the sides and bottom of the vessel, of a central vertically-disposed partition plate or bulk-head, and bracing means between said bulk-head and the sides, consisting of beams secured at their outer ends to the side plating and at their inner ends to said bulk-head bv vupper and lower complementary angle-plates, said upper plates having their vertical members slotted to receive the ends of the beams.
